What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction: The use of atherectomy in peripheral vascular intervention remains controversial. Aim: To review our experience with atherectomy as an adjunct to endovascular revascularization in a successive group of patients with chronic limb-threatening ischemia (CLTI). Material and methods: Consecutive patients with CLTI treated in a high-volume vascular center between 12/01/2019 and 12/31/2021 were reviewed. Follow-up data were abstracted from office and hospital records. Endpoints were death, all amputation, major amputation and target lesion revascularization (TLR). Secondary endpoints were relief of ischemic rest pain and healing of wounds. Results: During the study period 405 patients (447 limbs) underwent an endovascular procedure. Mean age was 77 ±11.7 years. Of the 447 limbs treated, 123 (27.5%) were Rutherford 4, 284 (63.5%) Rutherford 5 and 40 (8.9%) Rutherford 6. 1190 lesions (2.66 ±1.02 lesion per limb) underwent treatment, with 56.3% located in the femoral-popliteal distribution and 681 (57.2%) being total occlusion. During follow-up to 24 months, there were 76 deaths (18.8%) and 18 major amputations (4%). Surgical bypass was performed in 2% of cases. Estimated two-year amputation and major amputation-free survival probability was 88.4% and 94.5%, respectively. Estimated two-year TLR-free probability was 55%. Conclusions: Atherectomy facilitated treatment of patients with CLTI. These patients were elderly, with limited life expectancy and had multiple lesions per extremity with a high percentage of long occlusions and tibial disease. While TLR-free probability at 2 years was 55%, the overall amputation rate was low. This approach resulted in excellent limb salvage in a high-risk patient group with limited life expectancy and advanced disease.
